2 Claims.

This invention relates to an improved vibration dampener and front motor supports and is especially adapted for use in connection with Model A Ford automobiles.

At present in automobiles of this type springs connect between the front of the motor and the cross piece of the frame, including a suspension arch which more or less is associated direct with the springs, such suspension of the motor permits a rocking motion, which consequently throws the entire weight of the motor on one small spring at a time. This causes the springs to break, letting the motor down, throwing it out of alignment, and causing excessive vibration and wear, also causing wear on the main bearings, clutch and universal joint.

The purpose of the present invention is to entirely eliminate these disadvantages by means of supports which include double acting rubber cushions, both above and below to take care of the up and down shocks. In addition to absorbing the up and down shocks the motor is secured tight enough to the frame to eliminate excessive vibration.

Another purpose is to provide supports between the front of the motor and the cross member of the frame, so disposed in position adjacent the front of the motor and provided with beveled ends for abutting a shoulder on the front of the motor as to permit only one securing means for each support to be used, and thereby preventing any relative movement between the support and the front of the motor.

It is to be understood that the particulars herein given are in no way limitative, and that while still keeping within the scope of the invention, any desired modification of details and proportions may be made in the construction of the appliance according to circumstances.

The invention comprises further features and combinations of parts to be hereinafter set forth, shown in the drawing and claimed.

In the drawing:-

Figure 1 is a view in front elevation of a portion of a motor and the front cross member of the frame of the automobile, showing the improved supports as applied, illustrating the cushions in position.

Figure 2 is a sectional view on line 2-2 of Figure 1.

Figure 3 is an enlarged detail view of one of the supports.

Referring to the drawing l identifies a portion of the front of the motor, and which has a transverse rib 2 constituting an abutment at 3 for the supports 4. Each support 4 comprises an angle bracket, which is bolted at 5 to the front of the motor, in such manner that the inclined edge 6 will engage the abutment at 3, thereby preventing any pivotal action of the bracket relative to the front of the motor. The lower portion of that part of the bracket which is bolted to the motor has an offset part I to prevent any interference with other parts of the structure of the motor or the structure of the frame.

Each bracket includes a lateral portion 8, through which a long bolt 9 passes. The bolt 9 also passes through a rubber cushion l interposed between the lateral part of the bracket and a cross member ll of the frame of the automobile. The long bolt 9 also passes through the cross member of the frame and through a second rubber cushion l2, there being a washer [3 on the lower end of the long bolt, together with a nut l 4 threaded to the lower end of the bolt, thereby operatively so mounting the several elements relative to the cross member of the frame of the automobile, as to take the up and down shocks, and still fasten the front of the motor tight enough to the frame to eliminate any excessive vibration or rocking movements.

The invention having been set forth, what is claimed is:

1. In a vibration dampener and front motor support, the combination with an automobile frame having a front cross member and a motor on the frame, of a bracket secured to the front of the motor and depending therefrom, the lower end of the bracket having a lateral ear, cushions, one above and one below the cross member and axially incident to the lateral ear, and a bolt passing through the lateral ear through the cushions and the cross member and provided with means on its lower end adjacent the lower cushion for connecting the several elements, thereby compensating for lateral vibrations of the motor, and means constituting a part of the front of the motor and being engaged by the upper end of the bracket, thereby preventing any lateral movement of the bracket relative to the motor.

2. In a vibration dampener and front motor support, the combination with an automobile frame having a front cross member and a motor on the frame, said motor having at its front a transverse rib, of a bracket secured to the front of the motor and having an upper angle end edge engaging the rib thereby preventing any lateral movement of the bracket relative to the motor, the lower end of the bracket having a lateral ear, cushions, one above and one below said cross member, and axially incident to the ear, and a bolt passing through the ear and through the cushions and the cross member and provided with means on its lower end against the lower cushion to securethe several elements together.
